Benefits of technology

The patent describes a system and method for protecting the computer system state. It involves retrieving a list of files associated with the current system state and creating a signature for each file. These signatures are then compared to signatures of files from a previous system state. If the signatures match, the file is transferred. This helps to protect the computer system state from being tampered with or lost in case of a system crash.

Problems solved by technology

The large size of the system state dump can impose a burden on the backup software that needs to transfer data through network and store the data in a backup server, and for example, on storage media such as disk or tape.

Embodiment Construction

[0013]A system and method for protecting system or computer data are provided. Compared to the conventional or known methods, the system and method of the present disclosure, in one aspect, require less data to be transferred over the network from the machine being protected to the machine that is storing the system state data. The system and method of the present disclosure also may use less storage space in the backup server or servers compared to the conventional or known methods.

[0014]The Windows™ system state may include a registry, COM+ database, and system binary files under “Windows / system32” and other directories. System state data contains many elements of system's configuration that can be used to recover the system from a failure and restore the system to the state before the failure occurred. In Windows™ Server 2008 system, for example, the system binary files can occupy over six gigabytes of disk space. However, many of the system configuration files may not change fre...

Abstract

A method and system for protecting computer system state in one aspect generates signatures associated with system dump data, compares the signatures with those of the previous system dump data. Only those system dump data whose signatures are different from the previous dump are transferred for storing.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates generally to computer systems, and more particularly to protecting computer system states.BACKGROUND OF THE INVENTION[0002]Computer system state refers to the state of computer's operating system and its configuration at a given time. For instance, system state data may include system components such as the registry, COM+ Class Registration database, the files under Windows™ file protection, and boot files. Microsoft™ Windows™ counts system registry together with system databases and operating system (“OS”) files as “System State.” A system state may be backed up and recovered by storing and recovering the data that make up the system state, for instance, for system protection. Microsoft™ Windows™ provides Volume Shadow Copy Service (VSS) application programming interfaces (APIs) as a standard way to backup and recover the system state information.[0003]Windows™ system state data can grow very large in size. For example, a t...
